Stupid git. I know, I already raised my concerns regarding the new workflow, so I won't repeat that. I can understand (too some degree) that we don't want code to change just before the new merge window opens. But I do wonder if we really don't even want to do subject+description updates. Sure, the commit IDs will change. Who cares? Anyhow, it is what it is. -- Thanks, David / dhildenb
